Reseach on origin identification of commercially available Zaocys dhumnades / 中国中药杂志

ABSTRACT

Through market investigation, the adulteration of Zaocys dhumnades on markets was found out, and samples of authentic and adulterated Z. dhumnades on markets were collected. The origin and properties of the adulterated Z. dhumnades were studied in order to provide reference for the identification of Z. dhumnades. The counterfeit Z. dhumnades sold on markets were as follows: Ptyas korros, P. mucosus, Najanaja atra, Sinonatrix annularis, Dinodon septentrionalis, etc. It is found that there existed a obvious difference between the traits of the Z. dhumnades and counterfeits. Genuine Z. dhumnades with "sword ridge" "iron tail", strongly ribbed scales and other features, is the key point to identify the difference from adulterants.
